A primary object ofthisfinvehtioh is to provide forms whichare fuli adjustable as tolength, andwhi'ch may be" erected in ff'ers in order to attainany desiredwidth'or'height. I

'Another object or this invention is to provide novel means for keying oflocking the dilfrent sections of the forms together, this-means allowlngfbi absolutely rigid connection of theidiff erent sections and .allowinga great saving in time and labor-required to-erect a set of forms.

' Still another object o'f this'i'nvention is to provide concretefforrns which when corinected leave no" holes or eracirs, at" the "corners *or otherwise, thus enabling a more perfect wallform'ationj And a last ohjeet, to be mentioned specifi cally is to provide co'ncrete 'forms which'are'relatively inexpensive and practicable to manufacture, which are extremely safe; simple and con venient to use i'na Wide' variety "of construction, and which will give generally 'efii'ci'ent and durablese'rvice. i

With thes'e'bbjects definitely in' View, this invention resides in certain novel features" of con struction; combination and arrangement of ele merits and portions "as will be hereinafter'described in the specificatiom particularly pointed out in the appende'd clairns, andiilustrated in the accompanyingdrawings which form amaterial' part of this applic'ation, and in*which: V

Claims. (ems- 130 I 'Figure' liis an enlarged fragmentary view of the upper end of the structure shown in Figure 3. "Similar, oharacters" of reference I designate similar or' identical elements and portions throughout the specification and throughout the several Views; of the "drawings. f I v Referring now to the drawings in detail, this invention includes a plurality of outer elongated channel ipans '1 dinner elongated channel pans; l2 and waiersfM',-together with transverse members Iii, Corner lockjs', ltlffor'm ties 29 andla complement of supporting stakes 22; I a

The outer and inner elongated channel pans H) and lie-re very similar, each having a bd plate 24 and}? and. parallel laterally-disposed flanges 28 and'Sfl. The flanges 28 are preferably apertured at regularly spaced close intervals, while the fi'anges't'fl may" be similarly apertured but need not have an equal number of apertures, thatis', the apertures in the flanges 30 may tenregularly spaced as indicatedat' 34 in'Figure 6'. The walers- H are of simple strap form andmay be apertured as at 36 similarly to the inner pans,

and it sholild'be carefully noted that the pans and'walers are so dimensioned andth'e apertures are so. positioned that the apertures in' adjacent flanges and walers,- when the inner. pans are inser'te'd within" the outer pans and the wale'rs are insertedjwi'thinthe flanges oftheinner pans may be made'toregister. It will be obvious that this construction allows the length of a built up form to be varied at the will of the'operator.

A plurality of transverse members are pr0- vidd, these transverse i members having been referred to by the numeral i 6 and each preferably comprising a length-of angleiron with end plates 38 rigidly secured theretol 'One. end plate 38 has aipin 49 inserted 'therethrough'and rigidly secured thereto, while the other end plate 38.is apertured to'reclve 'a' loose pm 42 Which may be of'similar dimensions. It will be clear, how the transverse member'may be inserted within the inner'pan, with the pin inserted through registering apertures. in the adjacent flanges "28 and twandthe Wailers. l4, While the pin.42v.is similarly inserted after the transverse member is positioned; or roughly positioned, by the fixed. pin 40. "The transveis'elniembers iii to be used inside the inner-pans as in Figures 1, 2 and 3 are slightly shorter than; the transverse members i 6-.twhich are fiseainsme the Walers 14; as in "Figures 5 and9. I

Thei'corn'er key I 8 is comprised of two angle irons Al and '46 and two relatively large end plates 48 whichare aperture'd-asat' 50'. A. plurality of phase?" are used toconhect the corner key 18 within abutting portions" of the adjacent pins of inner pan l2 and outerpan l0, as clearlyindicated in Figure-6, when a corner construction is to-be erected;

When the forms are used, as in Figure 9, for the construction of a batter wall or foundation 52, the form tie 29 comprising a strap with an inclined portion 54, apertured as at '5 at'both ends, is used to tie the upper ends or sides of the forms, the pins 46 and 42 of the transverse members 55 being inserted through the apertures 56 of the form tie and through registering apertures in the outer pans and apertures 36 in the walers. It will be noted that the walers l4 are used to abut stakes 22, the stakes on one side of the forms being shown inclined according to conventional practice, as when a foundation 52 is being poured in an excavation 58.

The operation of this invention will be clearly understood from the foregoing description of the mechanical details thereof, taken in connection with the drawings and the above recitation of the objects sought to be achieved by this invention. In recapitulation and by way of further explanation of the uses to which the invention may be placed, reference may be had to Figure 5 wherein it is depicted how the forms may be used in tiers, walers being provided in pairs between the transverse members and the flanges of the pans. It will be clear how a wall of considerable height may be constructedby the use of these forms in tiers. It may be well to note that the transverse members IB function as supporting members and as dividing walls or end walls when and as desired.

Many minor variations in the exact construction and proportionment of the various elements of this invention may be resorted to without departing from the spirit and scope thereof and the scope of this invention should be determined only as limited by a proper interpretation of the terminology used in the subjoined claims.
